Above data were obtained by measurement using FDK's test circuits. |
Because the electrical specification of the description is a guaranteed
value when the voltage rating is input under
the ratings measurement condition, it is not value of the guarantee in
the range of the operation voltage and the range
of the operating temperature. |
